Instruction Manual

The terminals themselves are designed to allow the use of very heavy

speaker wire or connectors. Be sure to tighten them securely, but don't

over-tighten them.

WARNING: To prevent risk of electrical shock or damage to your

equipment, always switch off the amplifier or receiver when making

any system connections.

You can connect your speakers by using a variety of audio connectors such

as banana plugs (single or double), pin connectors, spade lugs, etc., or you

can:

1. Remove .5" of insulation from each wire end.

2. Twist the stranded wire together, keeping the two ends

separate.

3. Place the appropriate wire through the appropriate

postholes in the connectors. These holes are revealed when

you loosen the connector's capscrew.

4. Screw down the capscrew tightly, but be careful not to over

tighten it.

5. Check the tightness of the capscrews 24 hours after hookup

and occasionally after that, as they can loosen over time.

We recommend that you check your local electrical codes to make sure that

you are not using improper connectors.

It's important to observe polarity while making speaker connections: red

(+) terminals on the amplifier to red (+) on the speaker, black (–) on the

amplifier to black (–) on the speaker. Look carefully at the wires you are

using and note that one of the conductors of each pair will typically be

identified by color, printing on the outer jacket, ridges on the outer jacket,

or a thread intertwined with the wire strands. By convention, the marked

wire is connected to the red (+) terminal.

Whether your are connecting a complete system,or adding a single speaker

component to your present system, the wiring should look like one of the

system wiring diagrams on pages 7 and 8.

WARNING: Before turning on the amplifier, be certain that no stray

wire strands are touching across any terminals as this might damage

your amplifier.

Finally, check the polarity of your front speakers by listening to some ste-

reo music with good bass content. If the sound seems"hollow", unusually

spread out, or seem to have weak mid-bass, recheck your connections for

proper polarity and correct any out of phase connections,if necessary.

System Setup

Bass Management

Some older surround sound decoders and receivers offer a choice of "Nor-

mal"or"Wide-band"modes for the center channel speaker.The Model 8200

C is designed to be used in the Normal mode.Additionally,digital processing

multi-channel systems provide a Bass Management menu,which typically

requires you to select between "Small" or "Large" speakers during system

set-up. Since these systems have been designed to work with a dedicated

subwoofer,please set all the speakers in Systems 6200 and 8200 to Small.

To set these controls, sit in the prime listening position and have someone

switch between the compensation choices,using well recorded dialogue or

musical instrument recordings. Choose whichever switch position sounds

most natural and real to you.

NOTE: Although these controls have been designed to compen-

sate for various acoustic room anomalies, we recommend that you

try them to hear the difference that they make in the sound of the

system. For any number of reasons, you may decide that you prefer

them set in a particular manner inconsistent with your room's acous-

tics, but sounds best to you. Experiment. It will be worth it.
